Abstract
An electrode tube holding apparatus is mounted to an electric discharge machine (EDM). The holding apparatus is slidable upward and downward along with the spindle of the EDM and maintained within the midsection of an electrode tube for reducing the deformation of the electrode tube during its movement.
Claims4
An electrode tube holding apparatus for an EDM, the EDM having a main body and a rise-and-fall member slidably mounted to the main body, comprising:
- a gear wheel pivotably attached to the rise-and-fall member and having a post, the gear wheel and the post being rotatable along with the movement of the rise-and fall member;
- a cantilever slidably mounted to the main body and having at least one guide hole running therethrough for inserting an electrode tube mounted to the rise-and-fall member;
- and
- a rope having two ends connected with the cantilever and the post respectively;
- whereby when the gear wheel is rotated, the post is rotated to wind or unwind the rope to further drive the cantilever upward or downward.
